Add textShadows following implementation of boxShadows

Thanks, merged. but I prefer to keep more conservative comments with /* */

[Freddy03h]

Thank's for the merge !

For the comments, what's your configuration ? /* */ is broken in VSCode with reason-vscode.

Also, I'm new to Reason , but I find weird to see 'shadow and 'textShadow in ruleToJs at the same level with 'declaration and 'selector and can possibly grow with other "list rules" like shadow and textShadow. Any refactor idea to help ?

I'm not using VSCode so I can't help.
you're right for shadow and textshadow, I didn't realize that. I don't know what should be done right now, but it needs some reflexion.
